Las capas de la Tierra

The video explores the Earth's structure, starting from the inner core, a solid sphere of iron and nickel, to the outer core, which is liquid. It then describes the mantle, the thickest layer, and the crust, where we live. The crust is divided into plates that move slowly over the mantle, a process known as plate tectonics.

What is the significance of the Earth's crust and how is it divided?

Explain how the tectonic plates move and the rate at which they move.
